Abstract
Description
Technical Field
[0001] The utility model relates to the field of corn harvesters, in particular to a rear axle supporting device of a side-tilt discharging type harvester. Background Art
[0002] In the existing corn stalk and ear harvesting machines, most of the operations of dumping the hay bin and grain bin are concentrated on one side of the machine body. During the flipping process, the center of gravity of the entire vehicle will tilt to one side. After multiple dumping operations, the frame will have inconsistent heights on the left and right, which will aggravate the deformation of the frame and affect the product service life.
[0003] To this end, a supporting device can be added to prevent the frame from deforming during the tipping process of the hay bin and grain bin. Utility Model Content
[0004] The purpose of the utility model is to provide a rear axle support device for a side-tilting discharging harvester, which can prevent excessive deformation of the frame during the dumping of hay bins and grain bins and increase the service life of the frame.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A rear axle support device for a side-tilting discharging harvester includes a beam limiting slider, a slide rail, a telescopic assembly and a limiting connector. One end of the beam limiting slider is slidably connected to the slide rail, the other end of the beam limiting slider is hinged to one end of the telescopic assembly, and the other end of the telescopic assembly is hinged to the limiting connector. The top surface of the beam limiting slider has a protrusion that abuts against the bottom surface of the frame beam. The protrusion is used to support between the rear axle and the frame beam when the harvester is tilting to discharge materials, thereby offsetting the deformation of the frame beam in the tilting direction.
[0007] In a further solution, the other end of the telescopic assembly is hinged to the limiting connector via a limiting pin.
[0008] In a further solution, the limiting connector is fixedly connected to the lower end of the limiting pin, and the upper end of the limiting pin is locked by a pin.
[0009] In a further solution, the protrusion on the top surface of the beam limiting slider is close to one end of the telescopic component.
[0010] In a further solution, the top surface of the beam limiting sliding block is provided with a groove for avoiding the frame beam at one end away from the telescopic assembly.
[0011] In a further solution, a groove is provided in the middle of the slide rail, and an I-shaped slide is provided at the bottom of the beam limiting slider away from one end of the telescopic component, and the bottom of the I-shaped slide matches the groove and slides.
[0012] In a further solution, the beam limiting sliding block has a support near one end of the telescopic component, and the support is provided with a slot near one end of the telescopic component, and the telescopic component is hinged in the slot via a rotating pin.
[0013] In a further solution, the slide rail and the limiting connector are both fixedly supported on the side of the rear axle close to the side tilting discharge.
[0014] In a further solution, the telescopic component is a telescopic cylinder.
[0015] In a further solution, there is an installation space for the support device between the rear axle and the frame.
[0016] Beneficial effects of the utility model:
[0017] The utility model uses the telescopic assembly to extend and retract, driving the beam limit slider to slide along the slide rail, extending to the bottom of the frame beam at the rear axle. The protrusion supports the frame beam and prevents excessive deformation of the frame. The telescopic assembly also avoids the problem of small gaps between the beam limit slider and the frame, which makes it difficult to move the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] like Figure 1 A rear axle support device for a side-tilt discharging harvester includes a beam limiting slider 1, a slide rail 2, a telescopic assembly 3 and a limiting connector 4. One end of the beam limiting slider 1 is slidably connected to the slide rail 2, and the other end of the beam limiting slider 1 is hinged to one end of the telescopic assembly 3. The other end of the telescopic assembly 3 is hinged to the limiting connector 4. The top surface of the beam limiting slider 1 has a protrusion 11 that abuts against the bottom surface of the frame beam.
[0028] Its working principle or implementation method is as follows: Figure 1 and Figure 2 , the slide rail 2 and the limit connector 4 are connected as follows Figure 2 As shown, the rear axle 8 is close to the side-tilting discharge end. When the grain bin 5 and the hay bin 6 of the side-tilting discharge harvester are unloaded, the telescopic assembly 3 drives the beam limit slider 1 to slide along the slide rail 2 to the bottom surface of the beam of the frame 7, and as shown in FIG. Figure 6 As shown, the beam of the frame 7 is supported by the protrusion 11 that matches the beam of the frame 7, thereby improving the supporting strength of the beam of the frame 7, preventing it from excessive deformation, and increasing its service life. Instantly, the frame can be protected from excessive deformation at the rear axle due to roll deformation.
[0029] According to the above working principle, some embodiment structures or implementation methods are provided, such as Figure 1 As shown, the other end of the telescopic assembly 3 is hinged to the limiting connector 4 via a limiting pin 31. This hinged connection has a simple structure and is convenient for manufacturing and assembly.
[0030] The limiting connector 4 is fixedly connected to the lower end of the limiting pin 31 , and the upper end of the limiting pin 31 is locked by a pin.
[0031] like Figure 1 The projection 11 on the top surface of the shown beam limiting slide block 1 is close to one end of the telescopic assembly. Like this, an oil cylinder with a smaller stroke can be used, which also makes it convenient for the oil cylinder to be arranged.
[0032] like Figure 5As shown, the top surface of the beam limiting slider 1 is away from one end of the telescopic assembly and has a beam groove for avoiding the frame 7. This can prevent the beam of the frame 7 from interfering during normal operation due to too small a gap.
[0033] like Figure 4 As shown, a groove is provided in the middle of the slide rail 2, and an I-shaped slideway is provided at the bottom of the beam limit slider 1 away from the end of the telescopic component 3. The bottom of the I-shaped slideway matches the groove and slides. The I-shaped slideway has strong supporting force.
[0034] like Figure 3 As shown, the beam limit slider 1 has a support 12 at one end near the telescopic component 3, and a slot is set on the support 12 near the end of the telescopic component 3. The telescopic component 3 is hinged in the slot through a rotating pin 32. This hinged structure is simple and easy to manufacture and assemble.
[0035] The slide rail 2 and the position-limiting connector 4 are both fixedly supported on the rear axle near the side-tilting discharge end, which facilitates the arrangement of the telescopic assembly 3.
[0036] The telescopic component 3 is a telescopic oil cylinder. If necessary, a linear telescopic structure such as an electric cylinder or a pneumatic cylinder can be selected as an alternative.
[0037] There is installation space for the supporting device between the rear axle 8 and the frame 7. This facilitates the installation of the entire supporting device.
